Abstract

An adaptive filter designed to cancel pathological tremor in computer pen input is tested on-line. The adaptive filter, called the WFLC (Weighted-frequency Fourier Linear Combiner) filter, estimates tremor frequency as well as amplitude and then cancels the tremor. The WFLC algorithm was implemented into pen driver software and tested with subjects with pathological tremor. A standard low-pass filter which is commonly used to attenuate tremor was also tested and compared with the WFLC filter. Tests were conducted through a series of quantitative target objectives. Best results were obtained when the WFLC filter was used.
